As smartphones get more expensive and indispensable, the smartest thing to do is to safeguard them. Word to the truly wise: Get an iPhone case that not only protects your lifeline against dings and scratches but also protects your actual life—the case has a discreet space where you can hide two condoms.  
The Playa Case can be purchased for $29.95 in black, white or pink. It's a small price to pay for having protection at your fingertips.
